Description
OpenEMR before 8.4.0 contains an improper authorization vulnerability in the non-patient POST /fhir/DocumentReference/$docref route that allows low-privileged users to generate any patient's CCDA. Attackers with only demographics and documents permissions can supply a victim patient parameter, then download the full-chart CCDA from Patient Documents to exfiltrate clinical data.
